I have this piece and a few other Asian pieces that I may swap. What I like is African weapons {ceremonial/parade}, clubs, I still need a good wire covered knobkerrie. I would like a club from New Britian area, Solomans, Vanuatu. I would like one of the stone ball or disc clubs.
This piece is 43 inches ---- 108cm out of the scabbard. The blade is in very good condition etched showing all the pattern welded steel. The inscription relates to this period of production. 1806-10
ca . 1806 French Empire of Napoleon I
The word impériale is mentioned (Impale)
Mf ure Imp ale du Klingenthal Coulaux frères
Mf ure Imp ale du Klingenthal Coulaux
More information can be found at this site. It was suggested to me that this form of blade is not common even for Klingenthal production.

You can email or pm for more pictures. Sorry some of these are rather large for this site but it is a big sword.
